Android TabWidget in Light theme

Question

I have an application that targets the 1.5 framework and uses the default light theme. When using a tab widget with this theme, the tab images are barely visible, and the tab captions are quite impossible to discern, except for the currently active tab.

In the default dark theme these tabs come through quite clearly, but this is not a solution I'd be very happy with. Is there a simple setting I can set, that sets up the tab widget for better visibility in light themes, or would I have to tamper with images and text styles manually?

Answer 1

it's not pretty, but you can try this in your tab activity.

// light theme support
final TabHost tabHost = getTabHost();
tabHost.setBackgroundColor(Color.WHITE);
tabHost.getTabWidget().setBackgroundColor(Color.BLACK);

// hack to set font size
LinearLayout ll = (LinearLayout) tabHost.getChildAt(0);
TabWidget tw = (TabWidget) ll.getChildAt(0);

// first tab
RelativeLayout rllf = (RelativeLayout) tw.getChildAt(0);
lf = (TextView) rllf.getChildAt(1);
lf.setTextSize(21);
lf.setPadding(0, 0, 0, 6);

// second tab
RelativeLayout rlrf = (RelativeLayout) tw.getChildAt(1);
rf = (TextView) rlrf.getChildAt(1);
rf.setTextSize(21);
rf.setPadding(0, 0, 0, 6);

/res/values/colors.xml should have

<resources>
    <drawable name="black">#ff000000</drawable>
    <drawable name="white">#ffffffff</drawable>
</resources>

AndroidManiest.xml should have

<application android:theme="@android:style/Theme.Light">
